    About Philodendron ‘Xanadu’

    Philodendron 'Xanadu', also sold as Winterbourn and now classified botanically as Thaumatophyllum xanadu, is a clumping evergreen shrub rather than a climber. Deeply lobed glossy leaves radiate from a central crown on stiff stalks, building a mound of texture that holds its shape without staking or support.

    Bright filtered light or dappled shade suits it, in an organic, free-draining soil kept lightly moist. It grows 20 to 50 centimetres a year to about 1 to 1.5 metres tall and 1.5 to 2 metres wide. Frost damages the foliage, so keep it to warm temperate and subtropical positions or indoors.

    It is used in mass plantings under trees, along shaded walls, in tropical-style beds, in large pots at an entry and in atriums and offices. Flowers are rare and inconspicuous, a reddish spathe low in the clump. The value is dense, even foliage in shade with very little upkeep.

    Frequently Asked Questions

    About Winterbourn Philodendron

    What is Philodendron 'Xanadu'?

    Xanadu, also sold as Winterbourn, is a clumping evergreen foliage plant now placed botanically in the genus Thaumatophyllum. Unlike most philodendrons it does not climb. Deeply lobed glossy green leaves radiate from a central crown on stiff stalks, forming a self supporting mound that stays neat without staking.

    How big does Xanadu grow?

    It grows to about 1 to 1.5 metres tall and 1.5 to 2 metres wide, spreading wider than it stands high. Growth is around 20 to 50 centimetres a year in warm conditions. In mass plantings the clumps knit together into a continuous low layer, so allow roughly a metre between plants.

    Does it need sun or shade?

    Bright filtered light or dappled shade is ideal. It will take some morning sun, but hot afternoon sun bleaches and scorches the leaves, particularly in dry inland heat. In deep shade it grows slowly and the clump opens up. Indoors it wants a bright position near a window rather than a dim corner.

    Is it frost tolerant?

    No, it is frost sensitive and the foliage marks badly after a cold night. Keep it to frost-free positions in warm temperate and subtropical gardens, or use it under eaves, in courtyards and beneath tree canopies where the air stays warmer. In cooler districts it is best grown in a pot that can be moved.

    Can it grow in pots or indoors?

    Yes, it is one of the more reliable large-leaf plants for containers and interiors. Use a wide pot with free-draining mix, keep it evenly moist without letting it sit in water, and wipe the leaves occasionally so they stay glossy. Indoors it holds its form for years given a bright spot and light feeding.

    Is it safe around pets and children?

    No. Like other philodendrons, the sap contains calcium oxalate crystals, which cause burning and swelling of the mouth if chewed and can irritate skin and eyes on contact. It is not a plant for a household where pets or small children graze on foliage. Wear gloves when dividing or removing old leaves.

    How do I care for Xanadu?

    Plant into rich, free-draining soil with plenty of organic matter and mulch the surface. Water regularly through warm weather and less in winter, keeping the soil moist rather than wet. Remove older yellowing leaves at the base as they age. Feed with a slow release fertiliser in spring and divide congested clumps.

    Acmena smithii 'Firescreen' - Lilly Pilly

    Acmena smithii 'Firescreen' is a fast-growing Australian native lilly pilly selected for its brilliant red new growth, which flushes repeatedly through the warmer months against dense glossy green mature foliage. As an Acmena it is naturally resistant to psyllid, so the foliage stays clean without spraying.

    'Firescreen' grows to 4 to 5 metres tall and 2 to 3 metres wide with a naturally dense upright habit that fills in from ground level. Growth is quick at 50 to 90 centimetres per year once established, which makes it one of the faster ways to build a solid privacy screen along a boundary or between neighbouring houses.

    'Firescreen' performs across most of the Australian east coast and southern states, from tropical Queensland through to Melbourne and Adelaide. It handles full sun to part shade, tolerates light to moderate frost once established, and responds well to trimming, so it can be run as a loose screen or clipped into a formal hedge.

    Frequently Asked Questions

    About Acmena smithii 'Firescreen'

    How tall does Acmena smithii 'Firescreen' grow?

    'Firescreen' grows to 4 to 5 metres tall and 2 to 3 metres wide when left unpruned. It is easily maintained at 2 to 3 metres as a trimmed hedge, and holds its density right down to ground level.

    How fast does 'Firescreen' grow?

    'Firescreen' is fast-growing, adding 50 to 90 centimetres per year once established. In good soil with regular water through the first two summers it will form a usable screen within two to three years.

    Is 'Firescreen' psyllid resistant?

    Yes. 'Firescreen' is an Acmena, and Acmena species are naturally resistant to the psyllid that causes pimple-like galls on many Syzygium lilly pillies. This is the main reason it is chosen for large hedge runs.

    How far apart should I plant 'Firescreen' for a hedge?

    Plant 1 to 1.5 metres apart for a dense informal screen, or 80 centimetres apart for a tighter formal hedge. For an avenue effect allow 3 metres between plants.

    Is 'Firescreen' frost tolerant?

    'Firescreen' handles light to moderate frost once established. In colder inland districts protect young plants through their first winter, after which they harden off and cope with regular frost.

    Where does 'Firescreen' grow best in Australia?

    'Firescreen' performs from tropical and subtropical Queensland through coastal and inland New South Wales, Melbourne and surrounds, Gippsland, the Western District and Adelaide. It is one of the more climate-adaptable lilly pillies.

    When and how should I prune 'Firescreen'?

    Trim two to three times through the growing season to build density and keep lines crisp. Each cut triggers a fresh flush of red new growth, so regular light pruning gives more colour rather than less.
